PACKING ATTACHMENT FOR DISK HARROWS.

9 Application filed May 27, 1912. Serial No. 699,975.

To all whom it may concern:

Be it known that I, HERBERT R. ADAMS, a citizen of the United States,residing at Halstead, in the county of Harvey and State of Kansas, haveinvented certain new and useful Improvements in Packing Attachments forDisk Harrows, of which the following is a specification.

This invention relates to land-packer attachments for disk barrows.

The object of the invention is to provide a combined land packer andharrow which will simultaneously pack, and to some extent cultivate thesoil; and a further object is to provide a device of this kind that maybe kept tight upon the disks to which it is attached, regardless of thedecreasing diameter of a disk, caused by Working the soil.

To these ends the invention resides in the novel construction to bedescribed, and in order that said invention may be fully understood,reference will now be made to the accompanying drawing, in which:

Figure 1 is an elevation view of said attachmentin position upon a disk.Fig. 2 is a central section of the same, on line IIII of Fig. 1. Fig. 3is a detail view, sectioned on line IIIITI of Fig. 1.

1 designates a disk of the present standard shape; 2 the shaft or axleon which it is rotatably-mounted The attachment consists of two arcuaterim sections 3, each having therein a groove adapted to receive theperiphery of the disk 1. These sections are duplicates of each other,and each comprises a heavy rim 5, provided with a continuous series ofpyramidal teeth 6. The ends of each section are formed with co-fittingtongues 7 and grooves 8, and it is important that ample spaces as 9 beleft between the proximate ends, in order to provide for the sectionsbeing tightly fastened on the disk as the latter becomes smaller indiameter by wear. The sections are fastened together by hook-bolts l0and turnbuckles 12; the sec- Specification of Letters Patent.

tio-ns are provided with eye-lugs 13 for reception of the hooked ends ofthe bolts.

The teeth 6 are preferred to a continuous rim because the latter wouldmerely pack the soil, whereas the toothed packing rim operates tocultivate, as well as pack, the soil.

When the farmer is through using the packing attachments he removes themfrom the disks and may then use the harrow as such. When the packersections are reattached to the disks (which may then be reduced in size)the space 9 will permit said sections to be drawn against the diskperiphery by the turnbuckles.

In practice, suitable packing, such as canvas, leather, etc., may beinterposed between the cutting edge of the disk and the attachment toprevent the latter from dulling the former.

Having thus described my invention what I claim and desire to secure byLetters Patent, is: i

1. An attachment of the kind described, comprising two arcuate sectionseach having a groove to receive the periphery of a disk; each sectionhaving a heavy rim provided with a series of pyramidal teeth,andadjustable means to fasten said members upon a disk.

2. An attachment of the kind described, comprising two arcuate halves,each half comprising a heavy rim having an internal groove for peripheryof a disk, a series of teeth projecting from said rim, each of saidhalves being provided with tongued and grooved ends and with lugsadapted for at tachment of bolts, bolts adapted to engage said lugs, andturnbuckles for tightening said bolts.

In testimony whereof I affix my signature, in the presence of twowitnesses.
